Police say the two teens, one a 14-year-old girl and one a 15-year-old boy, knocked on the door of 74-year-old Verlee Butler, in the 2300 block of North Windsor Avenue in San Bernardino, shortly before 5 p.m. Monday.
When Butler opened his door, police said the two teens struck him, sending him to the ground. Once in the home they reportedly continued to strike him with their fists.
Butler suffered multiple non-life threatening injuries.
"They took cash and coins from the home then fled," police Sgt. Tim Crocker said. "Mr. Butler was treated at the scene by paramedics and refused to go to the hospital."
The two teens were identified and arrested without incident, police said. They were being held in Juvenile Hall in San Bernardino.
"This seems to have become a trend," Crocker said, referring to violence against the elderly. "And we're working to stop it."
